Irganox B 215 – a processing and long-term thermal stabilizer system – is a synergistic blend of Irgafos® 168 and Irganox 1010.

Irganox B 215 is used in polyolefins and olefin-copolymers such as polyethylene, polypropylene, polybutene and ethylene-vinylacetate copolymers. The blend can also be used in other polymers such as engineering plastics, styrene homo- and copolymers, polyurethanes, elastomers, adhesives, and other organic substrates. Irganox B 215 can be used in combination with light stabilizers of the Uvinul®, Tinuvin® and Chimassorb® range.

Features & Benefits

Irganox B 215 is a convenient blend addressing a range of stabilization needs. In the recommended applications Irganox B 215 provides significant benefits, such as

• long-term thermal stability
• low color formation
• maintenance of original melt flow

Irgafos 168 – an organophosphite of low volatility and particularly resistance to hydrolysis – protects during processing organic polymers which are prone to oxidation. Irganox 1010 – a hindered phenolic antioxidant – contributes synergistically to the stabilization of the polymer during processing and provides long-term thermal stability by preventing thermo-oxidative degradation during service life. Performance can be improved in synergistic combinations with other BASF additives (e. g. thioethers). Blends of Irganox 1010 and Irgafos 168 with Hydroxylamine FS042 are particularly effective.
